The Biebs and Stephen spent Monday in Grand Rapids, Michigan where the future father/son-in-law duo hit up a music festival. On their way back to the hotel, they had a touching moment -- placing their arms around each other. That oughta put a smile on Hailey's face.
BTW ... Hailey's giving her guys some dude time because she's busy at New York Fashion Week. She's kind of a big deal there.
